The 6 Most Earth like Planets.

6 Most Earth like Planets

Discovering the first true "alien Earth" is a long-held dream of
astronomers — and recent exoplanet discoveries suggest that their dream
will come true in the not-too-distant future.

All the planets that I am about to mention have similar atmospheric and
environmental conditions as Earth. These planets lie within the
“Goldilocks zone” meaning they are neither too hot or too cold to
support life. And even if there isn’t complete proof for the existence
of some of the planets

6. Gliese 581 d

This exoplanet, which lies just 22 light-years from Earth, is at least
4.5 times as massive as Earth, and researchers aren't sure whether or
not it's rocky. Gliese 667Cc completes one orbit around its host star in
a mere 28 days, but that star is a red dwarf considerably cooler than
the sun, so the exoplanet is thought to lie in the habitable zone.

A year lasts 66.87 days, so expect to spend a fortune on calenders. It
is also considered a cold planet since it has no proper atmosphere, but
to be fair if Earth had no atmosphere we would also have been considered
a cold planet with an average temperature of -18°C. In 2009 we beamed
25,880 messages from 190 different countries were sent towards its sun,
probably messages begging them not to invade us.

5. Kepler-69c

Kepler-69c, which is about 2,700 light-years away, is about 70 percent
larger than Earth. So, once again, researchers are unsure about its
composition.

A year is 242 days long, which so far is the closest we got to one
year on Earth. Sadly, today it seems to have common properties to Venus
which usually means, no chance of life naturally occurring there, ever.
It still doesn’t rule it out as a possible place to settle.

4. Kepler-62f

This planet is about 40 percent larger than Earth and orbits a star much
cooler than our sun. Its 267-day orbit, however, puts Kepler-62f
squarely within the habitable zone.

This planet is 1.4 times the size of Earth, its sun is slightly
smaller and cooler than ours, and it would appear to be of peach color
to the naked eye if you were to stand on the surface. It would have a
rocky surface but with high probability of water there as well. It is on
the target list of SETI for possible life. Sadly its 1200 light years
away from us, so the peach sun will have to wait.Source

3. Kepler-62e

Kepler-62e is a super-Earth exoplanet discovered orbiting within
the habitable zone of Kepler-62, the second outermost of five such
planets discovered by NASA's Kepler spacecraft.

Kepler-62e is an exoplanet believed to be a water world, orbiting at
about the equivalent distance of Mercury in its planetary system some
1,200 light-years from Earth. The planet is an exciting find to
exoplanet researchers because it is close in size to Earth, and also
orbits in the habitable region of its star (which is smaller and dimmer
than that of Earth's).

The planet is about 1.6 times the size of Earth and orbits its parent
red dwarf star about once every 122 days. It is actually one of two
possibly habitable planets in its system. Also present, but farther out
from the star, is Kepler-62f, which is about 1.4 times the size of
Earth.

2. Gliese 581 g

Gliese 581g is an extra-solar planet candidate within a planetary system
that is only 20 light-years from Earth, but at this point it is highly
doubted to exist. First announced in 2010 as a planet close to Earth's
mass in the habitable zone of its host star, the exoplanet has come
under scrutiny as other research teams cast doubts on its discovery.

Gliese 581d is the third planet from its host star in the Gliese 581 system, or the fifth planet if you include two
unconfirmed planets.

Gliese 581g is an unconfirmed exoplanet in the Gliese 581 system.

There are four confirmed and one other unconfirmed planet in the system.

The planet is the fourth in order from its red dwarf host star.

The mass indicates that it is probable Gliese 581g is a rocky planet with sufficient gravity to hold onto its atmosphere.

Gliese 581g is one of the most Earth like planets detected in the habitable zone of its star.

1. Kepler-452b

This world, whose discovery was announced last month, is the most
Earth-like planet found so far, NASA officials say. Its parent star is
very similar to our sun, and the planet orbits in the habitable zone. At
1.6 times the size of Earth, Kepler-452b has a "better than even chance" of being rocky, its discoverers have said. Kepler-452b resides 1,400 light-years from Earth.

Kepler-452b may be Earth's close cousin, but living on the newfound world would still be an alien experience.
A group of pioneers magically transported to the surface of Kepler-452b
— which is the closest thing to an "Earth twin" yet discovered,
researchers announced yesterday (July 23) — would instantly realize they
weren't on their home planet anymore.
